Mine is only 835kb. You can do a “Print Screen” and then from an image editing program, crop it. I have screen cap programs [for stills and video] and use them to do screen caps. The resolution is 72 DPI anyway, so try my suggestions. There are reasonable cap programs out there. I use “Screen Shot Standard” for stills and “Capture Wiz” for video. The later is great for capturing entire video w/audio.
Also have Photoshop, Flash and Illustrator. They’re expensive. I use them for my business: web development, graphic design & photography.
Hope this helps ya.
